Abstract:
This paper presents a kind of single-phase PWM rectifier based on current tracking control.According to the operation principle of the main circuit,a new control strategy is proposed.With an inner hysteresis current-loop and an outer voltage-loop control,the stability of the output voltage can be improved and the phase difference between the input voltage and current can be controlled as expected.On this basis,the choice of some important parameters in circuit design is put forward.The formula of switching frequency are derived by analyzing the principle of hysteresis comparison control.At the end of the paper,some simulation results are presented,which shows the feasibility and accuracy of the design.
